Gibraltar Z2430 Threaded Rest Button 3/8-24 Low Carbon Steel

Product Description

The GIBRALTAR Z2430 is a threaded rest button designed for use in fixturing, workholding, and precision positioning applications. It features a 3/8-24 thread with an overall length of 11/16 inches and a head height of 1/4 inches. Constructed from low-carbon steel with a black oxide coating, this button provides a hardened contact surface that resists wear and corrosion in light-duty shop environments. The 1/2-inch hex body allows for straightforward installation and adjustment with standard tooling. Machinists, tool and die technicians, and fixture builders install this type of component when establishing repeatable datums or support points on machined parts.

This rest button is suited for use in machine shops, toolrooms, and manufacturing environments where precise, repeatable part location is required. It threads directly into a tapped hole in a fixture plate or jig body, providing a stable contact point against a workpiece. The black oxide finish offers mild corrosion resistance for indoor shop use. Sold individually, this button fits applications requiring a compact, low-profile locating point.

Key Features

• 3/8-24 threaded shank for secure installation in tapped fixture holes
• Overall length of 11/16 inches with a 1/4-inch head height for low-profile seating
• Low-carbon steel construction provides adequate hardness for standard workholding contact
• Black oxide coating reduces surface corrosion and light wear in indoor shop conditions
• 1/2-inch hex body allows installation and removal with a standard open-end or box wrench

Compatibility

Designed as a standard threaded rest button for use in fixture plates, jig bodies, and workholding assemblies with a 3/8-24 tapped hole.

Installation Notes

Installation is performed by machinists or fixture technicians using a standard 1/2-inch wrench or hex key on the body flats. Ensure the receiving hole is clean and the thread is properly tapped to 3/8-24 before installation. De-energize or lock out any associated machinery before adjusting or replacing rest buttons in an active fixture. Do not overtighten, as low-carbon steel threads can be damaged by excessive torque.
